Science Team

Science, the perpetual frontier

What do we do?
Who are we?


Within the United States Fish and Wildlife Service (Service) there has always been a need for a sound, defensible scientific approach and response to various issues. This need is more apparent now than it has ever been. In an attempt to formally organize its collective efforts across the various Service offices that are involved with broad scale, scientific issues that would be best addressed utilizing a diversity of expertise, Region 1 of the Service formed the Science Team (ST). The Science Team was formed in May 2003. It consists of nine members, all from the USFWS with representation from Fisheries and Ecological Services as well as Region 1 and Region 6.

What does the Science Team do?

The ST receives direction from the regional office (RO). If the RO determines that a given issue is scientific in nature, substantial in scope, and requires the collective (rather than specific or local) scientific expertise of the Service then the RO may choose to involve the ST. Through a comprehensive assessment, analysis and review of the best available science, the ST serves to provide a sound approach and defensible response to various scientific questions facing the Service. Products from the ST allow the Service to make policy or management decisions based on the best available science. Products from the ST are peer-reviewed by experts from (for example) federal agencies, states, tribes, academia and industry. The rigor of this process helps insure that Service decisions concerning the management and conservation of a species or ecosystem are well informed by the available science.
